I've been using this set since I started OU ( not a long time ago) and i've loved it. But I don't get how Heatran gets Stealth Rock when Gallade is faster and OHKOs with Close Combat unless Heatran outspeeds with a Choice Scarf, which means you are wasting the potentional of Heatran. In order to survive, it needs to either be running max HP, max Def, and a +Def nature, which i'm fairly sure no one ever runs, and even then it can be OHKOed (88.6% - 104.7%). So the only way Heatran can gurantee to set up Stealth Rock is to run either Chople Berry, which reduces it to 72.8% - 85.8%, which isin't much better. The final option is Focus Sash, but then your restricted to using it as a lead to make sure your Sash won't become a waste of an item.
